Question

Ba->BaO->Ba(OH)2+HNO3

Answer 1

2Ba + O2 = 2BaO
BaO + H2O = Ba(OH)2
Ba(OH)2 + 2HNO3 = Ba(NO3)2 + 2H2O

Answer 2

The chemical reaction you've written involves the reaction of barium (Ba) with nitric acid (HNO3) to form a series of products: barium oxide (BaO) and then barium hydroxide (Ba(OH)2).

The balanced chemical equation for this reaction would be:

Ba + 2HNO3 → Ba(NO3)2 + H2O

In this reaction, barium (Ba) reacts with nitric acid (HNO3) to form barium nitrate (Ba(NO3)2) and water (H2O). There is no mention of barium oxide (BaO) or barium hydroxide (Ba(OH)2) in this reaction. If you were specifically looking for a reaction that involves these compounds, please provide more context or details, and I'd be happy to assist further.
